Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Tuesday 9th June)

Best Days: Every day besides Tuesday week

This week and next week (Jun 10 - 19)

After a great run of swell over the weekend and into today, we've got another strong pulse of S/SW groundswell due to build this afternoon, peaking overnight and then easing into tomorrow.

This was generated by a broad and vigorous frontal system pushing towards WA late last week and should kick exposed breaks back to the 6-8ft+ range on dark today, easing from a similar size at dawn tomorrow, down to 6ft+ later in the day and smaller Thursday.

The easing trend will be halted into Thursday afternoon and early Friday but the arrival of a moderate sized and inconsistent long-range S/SW groundswell, keeping exposed breaks topped up with 4-5ft+ sets before dropping into Friday afternoon.

Conditions will continue to be best at exposed spots around dawn (with early variable winds) and on the protected reefs for the rest of the day with fresh and gusty E/SE trades.

Into the weekend, one final pulse of decent SW groundswell is due ahead of a quieter period into the following week.

This has been generated by an intense cut-off low in the Indian Ocean the last couple of days, aiming a small but intense fetch of gale to severe-gale SW winds towards us.

This swell should peak Saturday to a good 5-6ft across exposed breaks, with the chance for the odd bigger bomb, easing back slowly into Sunday and further next week.

For the remainder of next week background levels of long-range SW groundswell should keep exposed spots active, while more protected breaks will be small to tiny. The mornings will be best with variable breezes before the trades kick in.

Longer term a new large S/SW groundswell is on the cards for the 23/24th of the month, but we'll have a closer look at this on Thursday.
